JOIST-HANGER.

SPECIFICATION forming part of Letters Patent No. 753,053, dated February23, 1904.

Application filed July 10, 1903. Serial No. 164,953 (No model.)

' To all whom t may concern,.-

Be it known that LAUeUsT H. EBERLLARDT, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga 'and State of Ohio,have invented a certain new and useful Improvement in Joist-Hangers, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings.

The object of this invention is to provide a joisthanger which shallcombine lightness with strength, being simple and cheap in constructionand eiiicient in service.

The joist-hanger is made out of a single piece of sheet metal bent intosuitable shape and held by rivets.- Its particular form is hereinaftermore fully explained, and its essential characteristics are set out inthe claims.

In the drawings, Figure l is a front elevation, partly broken away, ofmy joist-hanger. Fig. 2 is a side elevation thereof, and Fig. 3 is aview of a blank from which the hanger is made. Fig. 4 is a perspectiveview of the hanger, and Fig. 5 is a bottom view.

The same letters of reference designate the same part in each figure.

Thevblank from which my hanger is made is a piece of sheet metalpreferably of substantially the same thickness throughout, which is cutinto the form shown in Fig. As shown in this ligure, the blank may beconsidered as composed of a back portion l, flaring side portions 2 2, atop portion 3, and a bottom portion 4, having wings 5 5. These variousportions are adapted to be bent upon each other at right angles, asindicated by the broken lines between them, thus bringing them into therelative positions shown in Fig. 4.

' On the lower ends of the side portions 2 2 are formed tenons 6 6, andbetween the bottom portion 4 and the wings 5 5 are formed openings 7 7.When the bottom portion is bent at right angles to the back, the tenons6 6 pass into the openings 7 7 and have their extreme ends rivetedbeneath the bottom portion 4. The two wings 5 are bent up onto the outersides of the side portions 2 and are there held by rivets 10. Y n

Across the junction-line of the top portion 3 with the rest of thehanger are formed elongated dents 8, which serve to reinforce andstiifen the bend between such portions. Suitable holes (indicated by 9)are made in various points of the hanger to allow the passage of nailso'r screws. Y

It will be seen that my hanger is very simply and cheaply made, beingsheet metal suitably punched and bent. ample, are made simply bypunching slots of the form shown in the sides of the plate. The tenonsand rivets make the hanger amply strong at the lower end, and the upperend by reason of the thickness of the metal and the reinforcing-dents isalso sufficiently stiff and strong.

I claim- The tenons 6, for ex- 1. A sheet-metal j eist-hanger having aback i' portion, integral side portions with tenons on their lower ends,and an integral bottonrportion having holes to receive said tenons,substantially as described.

2. A joist-hanger having a back portion, side portions with tenons ontheir lower ends, and a bottom portion having holes to receive saidtenons, said bottom portion having wings which are bent upward onto theouter side of said side portions and there secured, all of said partsbeing made of a single piece of sheet metal, substantially as described.

3. A sheet-metal joist-hanger consisting of a back plate and side platesbent forward therefrom, and a bottom plate bent forward from the backplate and carrying at its edges wings bent upward alongside of the sideplates and secured thereto by rivets, substantially as described.

4. A joist-hanger made of sheet metal and consisting of a back plate, atop plate bent rearward therefrom, sideY plates bent forward from theback plate, and a bottom plate bent forward from the back plate andhaving wings bent upward from its edges and secured to the side plates,substantially as described.

5. A joist-hanger made of sheet metal and consisting of a single blankform bent to comprise a back plate, a bottom plate, side plates tenonedinto the bottom plate, wings on the bottom plate bent upward on theouter sides of the side plate and atop plate bent rearward from the backplate, substantially as described.
